In a three-year project that launches this month, Natalia Nikolova, an electrical and computer engineering professor, will be working with researchers from Canada and Ukraine to design devices that use radar signals to analyze the materials carried by a person. The technology — which can be built into a military vest or a tripod, for example — is designed to emit radio waves that reach a person. The waves that bounce back will carry unique information that can be analyzed by computers. "This radio wave, as we say in radar terminology, interrogates the person and it carries back information from...
